Question statement

The elevation above sea-level of an orogen was estimated at different points in the past. The values were tabulated as shown below:

Time from the present (Ma)	$-10$	$-9$	$-8$	$-7$	$-6$	$-5$	$-4$	$-3$	$-2$	$-1$
Elevation above sea-level (km)	{{graphplot}[0]}	{{graphplot}[1]}	{{graphplot}[2]}	{{graphplot}[3]}	{{graphplot}[4]}	{{graphplot}[5]}	{{graphplot}[6]}	{{graphplot}[7]}	{{graphplot}[8]}	{{graphplot}[9]}

Give any introductory information the student needs.
